The through-hole endface of body opposite side is sealed with permeability magnetic material, and permeability magnetic material is externally provided with the sensor that can incude magnetic signal, described
Sensor is electrically connected to the control system.
The sensor for incuding magnetic signal is Hall sensor or tongue tube.
Preferably, the magnetic material is magnet.
The permeability magnetic material is to be threadedly coupled or be pressed in permeability magnetic material on the second cylinder body by screw with the second cylinder body.
The oil inlet includes at least one.
Preferably, the permeability magnetic material is the permeability magnetic materials such as stainless steel, copper, aluminium.
The outage is connect with flowline, and check valve is equipped between outage and flowline.
Sealing ring is equipped between the permeability magnetic material and the second cylinder body.
Magnet is arranged in the end of plunger in high-pressure plunger of the invention, and in cylinder body end face setting permeability magnetic material and suddenly
That sensor, during plunger moves to left fuel-displaced, the magnet and permeability magnetic material of plunger end, which bump against, generates magnetic signal, and then by suddenly
Magnetic signal is transferred to control system by that sensor, to realize the real-time detection fuel-displaced to high-pressure plunger, while can also be to high pressure
The oil pump capacity of plunger pump is monitored, with to high-pressure plunger oil pump capacity and the fuel-displaced time rationally controlled, guarantee plunger
Continuous normal work, avoid unnecessary oil mass from wasting, while avoiding observation monitoring artificially fuel-displaced to plunger pump, and
When oil leak occurs in plunger pump, staff can reduce judge whether oil leak and oil inlet are reduced according to oil pump capacity, into
And certain measure is taken, corresponding monitoring effect is also played to oil leak or oil inlet quantity to a certain extent.The configuration of the present invention is simple,
It is convenient to operate, and avoids the waste of oil mass, while having saved human cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
To more fully understand those skilled in the art to the present invention, the present invention is done With reference to embodiment
It further illustrates:
As shown in Figure 1, a kind of fuel-displaced detectable high-pressure plunger, including cylinder body and plunger, cylinder body is interior to be equipped with through-hole, and plunger is set to
In the intracorporal through-hole of cylinder, the cylinder body consists of two parts, the first respectively cylindrical cylinder body 2 and with its integrally formed the
Two cylinder bodies 1, plunger are divided into the first plunger 4 and the second plunger 6, and the intracorporal through-hole of cylinder is divided into first chamber 5 and by plunger
Two chambers 9；First cylinder body 2 is equipped with oil inlet 3, and the upper side of the second cylinder body 1 is equipped with outage 14, second plunger
6 are equipped with oil outlet 7, and reset spring 8 is arranged on the left side axis body of the second plunger 6, and the end of left side axis body is equipped with magnet 10,
It is fixed with permeability magnetic material 11 in second cylinder body 1 with the through-hole endface of 2 opposite side of the first cylinder body, permeability magnetic material is by cylinder body
Interior through-hole one end sealing, permeability magnetic material 11 are externally provided with the sensor 12 that can incude magnetic signal, and the sensor 12 is with control
System electrical connection.
The sensor 12 for incuding magnetic signal is Hall sensor or tongue tube, and Hall sensor and tongue tube have
The features such as contactless, low-power consumption, long life, high response frequency, can reliably work under all kinds of adverse circumstances.
It is to be threadedly coupled or permeability magnetic material is pressed in the second cylinder by screw between the permeability magnetic material 11 and the second cylinder body 1
On body 1.
The oil inlet 3 can set one, may also set up it is multiple, if when multiple oil inlets, multiple oil inlets are annularly uniform
It is distributed in the first cylinder body, the oil inlet simultaneously of multiple fuel feed holes can guarantee the uniformity of the speed of oil inlet and oil inlet distribution into cylinder body,
Improve plunger pump working efficiency.
The permeability magnetic material 11 preferentially uses stainless steel copper or aluminium, and the magnetic conduction effect of stainless steel and copper aluminium is preferable, energy
Magnetic signal is more rapidly and accurately passed to the sensor of induction magnetic signal, then signal is transferred to control system, with realization pair
Fuel-displaced real-time monitoring.
The outage 14 is connect with flowline, and check valve is equipped between outage 14 and flowline, plunger pump can be made to exist
When fuel cut-off, high-pressure oil pipe and the intracorporal cavity of cylinder are completely cut off, prevent the oil in high-pressure oil pipe from blowing back into plunger pump.
Sealing ring 13 is equipped between the permeability magnetic material 11 and the second cylinder body 1, to guarantee the closing property of sealing of cylinder body through-hole.
High-pressure plunger of the invention is an element in high-pressure plunger pump, at work, as shown in Figure 1, firstly, oil
The intracorporal first chamber 5 of cylinder is entered from oil inlet 3, while the first plunger 4 pushes to the left, to the left by the oil in first chamber 5
It promotes, after the first plunger 4 is pushed into block oil inlet 3 to the left, continuation pushes to the left, while the second plunger 6 is made in thrust
It is moved to the left under, when the second plunger 6 is moved to after oil outlet 7 communicates with second chamber 9, oil enters second from oil outlet 7
Chamber 9, and then be discharged again from the outage 14 on the second cylinder body 1, realize fuel-displaced purpose, at this time the left side shaft end of the second plunger 6
The magnet 10 in portion is mobile to generate magnetic signal through permeability magnetic material 11, and the magnetic signal of generation is passed to control system by Hall sensor 12
System is to realize the fuel-displaced carry out real-time monitoring to plunger pump, and when oil is after the discharge of outage 14, reset spring 8 pushes the second column
Plug 6 moves right, while controlling the first plunger 4 and also moving right, after fuel feed hole 3 is communicated with first chamber 5 again, first
Chamber 5 forms vacuum, and oil mass enters from fuel feed hole 3 again, and then the first plunger 4 pushes oil to be moved to the left again, repeats above-mentioned
Fuel-displaced purpose is realized in movement again.Movement is looped back and forth like this, when fuel-displaced every time, the magnet 10 of 6 end of the second plunger can be with
Permeability magnetic material, which bumps against, generates magnetic signal, and then magnetic signal is transferred to control system to realize real-time monitoring column by Hall sensor
Plug pumps out the purpose of oil.
